Embodiment 1

[0019] Embodiment 1: the production technology of application shape hoop combined ventilation duct, as figure 1 and Figure 4 As shown, the steps of the process are: step 1, making the air duct plate, step 2, cutting the air duct plate, step 3, bonding the air duct plate to form an air duct; the bonding process of the air duct plate is: a. Place the lower air duct plate 1 horizontally, glue the left and right air duct plates 4 on both sides of the lower air duct plate, then glue the upper air duct plate 3 between the left and right air duct plates 4, and place the several The shape hoop 8 is inserted from the lateral sides of the upper air duct plate 3 to fasten and surround the left and right air duct plate 4 and the upper air duct plate 3. After the binding is completed and the positioning is correct, remove the shape hoop, and finally the adhesive After curing, remove the strapping 5 . The ends of the lower air duct plate 1 and the upper air duct plate 3 are misaligned ...

Embodiment 2

[0022] Embodiment 2: The process of cutting the air duct plate is: I, cutting each air duct plate according to the preset size; II, cutting the left and right air duct plates 4 and the upper and lower air duct plates to form a cutting seam 9 respectively. The distance from the cutting seam 9 to the mating edge is the thickness of the air duct plate, and the depth of the cutting seam 9 is three quarters of the thickness of the air duct plate. After transporting each air duct plate to the place where the combined air duct is pre-installed, cut two L-shaped grooves on both sides where the left and right air duct plates 4 cooperate with the upper and lower air duct plates. The inner fiber-reinforced inorganic viscose layer 7 and the heat insulation board 6 are removed at the mating edge, and the outer fiber-reinforced inorganic viscose layer 7 is retained, and two L-shaped groove mating edges are formed on the left and right air duct plates 4 .

Abstract

The invention relates to a production method of a ventilating duct by using shaped hoops, which comprises the steps of (1) preparing a ventilating duct plate; (2) cutting the ventilating duct plate; and (3) bonding the ventilating duct plate to form a ventilating duct. The bonding process of the ventilating duct plate comprises the steps of: laying a lower ventilating duct plate, bonding a left ventilating duct plate and a right ventilating duct plate at two sides of the lower ventilating duct plate, bonding an upper ventilating duct plate between the left and the right ventilating duct plates, inserting a plurality of shaped hoops from the transverse two sides of the upper ventilating duct plate to tighten and surround the left and the right ventilating duct plate and the upper ventilating duct plate, tying with a tying band along the transverse direction of the respective ventilating duct plate, positioning, removing the shaped hoops, solidifying with a bonding agent, and removing the tying band. In the inventive production method, during bonding and solidifying processes, the shaped hoops are used for fixing the ventilating duct plates to prevent the ventilating duct plates from swinging, then the ventilating duct plates are tied by the tying band, and then the bonding site of the four ventilating duct plates are tightly bonded, so as to ensure leak tightness.

Description

【Technical field】 [0001] The invention relates to a production process of ventilation ducts applied in the field of construction or air conditioning, in particular to a production process of combined ventilation ducts using shape hoops. 【Background technique】 [0002] At present, a ventilation duct represented by a combined glass magnesium air duct uses a foam board as a carrier, and glass fiber magnesium oxychloride cement is respectively compounded on the two sides of the foam board to make each independent air duct board, and then each air duct board is The tube plate is assembled and bonded by adhesive materials to form an air duct. During the process of bonding and curing, the air duct plate is prone to deformation, resulting in weak or incomplete bonding, which affects the sealing performance. The applicant has applied for a The patent that the strap is fixed so that it does not deform. However, when the air duct is bundled with the strap, the adhesive is not cured, a...
